JOHN W. DAVENPORT, OF CUMBERLAND CITY, ASSIGNOR OF ONE-HALF HIS RIGHT TO J. H. SULLIVAN, OF SHILOH, TENNESSEE.

IMPROVEMENT IN SHlNGLE-SHAVING MACHINES.

Specification forming part of Letters Patent NO. 201 503, dated March 19, 1878; application filed January 16, 1878.

following is afull, clear, and exact description thereof, reference being had to the aoc0n1- panying drawings, and to the letters of reference marked thereon, making a part of this specification.

The nature of my invention consists in the construction and arrangement of a machine for shaving shingles by hand-lever power, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure 1 is a plan view of my machine. Fig. 2 is a longitudinal section of the same.

A represents a bed-frame of suitable construction, upon which are secured two parallel beams, B B, connected at one end by a headpiece, O, as shown. The beams B B have on their inner sides longitudinal grooves to receive a sash, D, to a cross-bar, D, in which are attached two knives, a and b.

The sash D is, by means of two rods or bars, cl (1, connected with one arm of an elbow-lever, E, which is provided with a third arm, 0, extending downward, and pivoted in a mortise made in a bar, A, extending from the main frame A.

It will be seen that the sash D is moved back and forth in the guides B B by working the long arm of the lever E.

Below the sash in the main frame are formed two beds, G G, which are made inclined, as shown in Fig. 1, and deeper at one end than at the other, as seen at w and y in Fig. 2. Inside, from the head-piece O, is secured an abutment, H, under which the knife to passes.

This machine is portable, and can be moved to the timber with very little trouble, and secured to two sills. The knife a, on the back part of the sash, is to cut and staighten the edge of the shingle byholdin g the same against the abutment H-. The other knife, Z1 shaves the shingles.

The timber is first fed in the deep side w of .the bed, and then turned over to the other side and finished.

The knife I; that finishes the shingles is made with inclined cutting-edge, to pass easier through the timber and prevent splintering.

The machine may be made long enough to dress staves. 7

Having thus fully described my invention, what I claim asnew, and desire to secure by Letters Patent, is

1. In ahand-power shin gle-machine, the combination of the reciprocating sash D with knives a 1), beds G G, and operating-lever E, substantially as and for the purposes herein set forth.

2. The abutment H, in combination with the sash D and knife a, as and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 3d day of December, 1877.

JOHN W. DAVENPORT.
